First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.
-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.
So now we solved those and we got this answer: 2.11
Now, we need to subtract and re-write the expression.
2.11 - (-7.423) = 2.11 + 7.423= 9.533
Ok....so now we have our final answer, and we have the choices above.
The only answer that matches ours is the last one.
Final answer: 9.533

Its either A or B but my bets are on A
There tried too draw it out of you
N= -7; open the first bracket, then add the two negatives.Then open the second bracket, and cancel opposite sign 3's and then solve.
We can actually undsitribute the y
divide both sides by
times the right side by (ab/ab)
y=ab
You simply multiply 4 by 5 and get 20. :)
